go get any intended version

---

Whilst writing your own GO libraries, we GoPhers have a sound understanding of the packages and GO modules. but somehow when making our own libraries we tend to miss out on a small detail that can limit your versioning on git. I have put this up just so that you can benefit from my experience / exploration of solutions on the internet.

Lets see the problem first hand and then I bring out the solution/tweak.

We are writing this small uni-file library (for brevity sake Im assuming we have this small library)

go mod init github.com/kneerunjun/mylog

dpkg -l | grep -i docker
sudo apt-get purge -y docker-engine docker docker.io docker-ce docker-ce-cli
sudo apt-get autoremove -y --purge docker-engine docker docker.io docker-ce
sudo rm -rf /var/lib/docker /etc/docker
sudo rm /etc/apparmor.d/docker
sudo groupdel docker
sudo rm -rf /var/run/docker.sock

What is the need of getting such upstarted services on linux ?

---

I have tested a code working fine on my Raspbery. While much of effort has gone into hardware debugging and getting the ports to work as expected, It still is a challenge to run this program evrytime I have to showcase things to people.Fo each instance I have to connect the hardware along with the peripherals and then carefull issue commands to start the desired program

1. Logistics of the peripherals is cumbersome
2. Peripherals sdo consume more amperage

Would it not be good if there was a way th program upstarts with the machine itself ?

Or one up - wait for me in suspension to get started and sensing.

• Design Automation using CATIA VBA

  • Pre requisites

    • Mechanical design fundamentals
    • Mechanical Computer Aided Design (CAD)
    • VB.NET syntax, OO programming
    • Understanding of COM principles & Interface based design

  • The need for CATIA v5VBA (Why) :

    • State: CATIA is authorititive/popular CAD tool used for virtual mechanical design. Althought when it comes to repititive tasks that need precision it can get some assitance from the CATIA VBA tools.
    • VB code run without human interventions atop CATIA (CATIA VBA) leads to better efficiency + precision.Saves time for the engineers so that they can concentrate on higher, more innovative tasks.
• For large engineering organizations,since the business logic becomes **less

Getting docker started on Linux machine

Like me I expect you to have a Linux machine running atop VMbox that may inturn running on either Win10 or Mac. This also means that you have a linux machine already and all your docker commands are fired from a linux machine. Which gets me to the straight point - no need for docker-machine commands

Installing docker on your linux machine

Im using Anteregos(Arch) with Gnome desktop
